Default Re: Are there any Ex GPO engineers here? Dorman Lamps

So near, and good recall, they are 5v 0.09A. I assume they went for 5v to allow for the volt drop within the flasher circuit, I guess the static lamp's bulbs were slightly overdriven.
I seem to remember that torches that ran on 2 D cells had a 2.5v bulb, so maybe that was the practice to slightly overdrive them, maybe for a whiter light?
